The importance of a scientific drilling program to study active fault zones and earthquakes has been emphasized in numerous workshops and symposia, including the 1978 Los Alamos, New Mexico, Workshops on Continental Drilling for Scientific Purposes and 1974 Workshops on Continental Drilling held art Ghost Ranch, New Mexico. This report, prepared by the Panel on Downhole Physical Property Measurements and Fault-Zone Drilling of the Continental Scientific Drilling Committee, both reinforces and expands upon earlier recommendations and provides examples of possible sites. In this report, we explain briefly the scientific rationale used tin selecting each of these sites, the specific objectives of each hole, and the types of measurements that should be made both in situ and on recovered rock and fluid samples. In a final section we discuss methods for long-term deployment of downhole instruments for ultraquiet seismic, strain, and fluid monitoring. Such observations will make it possible to study active tectonic processes directly and to monitor them over time. 24 refs., 8 figs.
